S65 or wait for S55

I wonder about the new lighter M3, vs. the current one. Light weight does so much for handling and braking not to mention acceleration. One reason I am keeping the S54/z4M-R, at 3200 lbs.
I am torn about turbos and the associated complexity and potential to be further disconnected (the F30 is being ripped by Road & Track for being numb). Of course the M3 always remedies the current main 3 series ills with a race bred car.
I want to belly up for an S65 but... reading about crank/bedplate, oiling and other issues makes me wonder about the long term potential for issues (I hold onto cars long after they're paid for) that will rear their ugly head. I realize every series has some issue, but I feel I may have to wait to see what the new M3 is about, and then settle for a lightly used e9x if that's the obvious (better) choice.
I just can't bring myself to buy it blind. Something tells me to wait.
Thoughts?
Anyone else in this dilemma?

talking to friends at the CCA and various sites, they are said to be targeting the weight of the E46 M3, with an underhood pic of the engine. S55 looks complicated/ lots of plumbing and with the liquid cooled intercooler.
(had to debadge the pic, eh, Sticky)

I traded my 335i for a M3 a few months ago, I love the look & sound of the E92 M3 - it really doesn't get much better than that. But in terms of straight line performance, I question my choice of 'upgrade' every day. Maybe the new turbo'd M3 would have been a better fit for me - maybe I'll trade up again in it's second year production run; that's if I like the look of it (I'm not feeling the new generation BMWs).

Just tune it or supercharge it. The car runs mid 12's stock how fast do you want to go?

that's how I felt about the e9x models (have an e46 still).
but the pics I've seen make the new M out to look quite menacing.
not sure if that's good or bad.
Usually if I like something right away it's not always good for the long haul. the opposite is also true.
I am quite interested in how they dial out turbo lag.
A friend at a dealer said there are rumors about a third electric turbo that keeps the exhaust driven turbos up at all times
?

OP -- It depends how you like your M honestly. If you want a high revving screamer that has one of the best sounding exhaust notes I've heard, get the E9x/S65 powered M3. If you would rather have low end TQ & are a sucker for the new tech toys, wait until the new F3x M3/M4 comes out.

While both cars will wear the M3 badges, the changes made between the E9x & F3x are going to be the most substantial & "revolutionary" when compared against previous models

My bet is that the S55 will rev to 8000 also, knowing the M fanatical engineers....
i too enjoy the S65's v8 sound

No shot it'll rev into the 8s, prob redline somewhere closer to 7k like all the other high power, twin turbo 6-cylinder cars (GTR, the 997.1 & 997.2 Turbo Porsches). Especially considering the S63 Tu redlines in the 7k area (losing ~1.5k RPMs from the S85), the next gen M3/M4 will prob follow a very similar path.

BUT in all honesty it really sounds like you made you've already made up your mind & that you're gonna wait for the next gen M3/M4.

You probably wouldn't want to get a first year model anyway; it'll likely have it's issues. Get the S65 now, enjoy the sounds, and if you're at sea-level, you'll have around 45hp more than me stock for stock

My biz partner has a 997.1 Turbo, and it sounds very humble compared to the M3... which is good, because that's about the only thing I can outgun him on right now (maybe looks, but that's subjective).
